To all 'whom t may concern: l f

Be it known that we, CHARLES TURNER and HARRY J. FLOOD, citizens of the United States, and residents of Chicago, county of Cook, and State of Illinois, lhave invented certain new and useful Improvements in lowing is a specication, and which are illustrated in the accompanying drawings, forming a part thereof. f v

The lnvention relates to an apparatus for extracting oil from garbage and other materials and to that type o device in which the oil is extracted by the use of a solvent, the operation being carried on continuously, the material to be treated being delivered' to and discharged'from `the machine without interruption.

The Iobjects of the invention are to generally improve devices of this character,

creased eiiiciency. The characterof t-he invention is fully hereinafter pointed out and is shown in the accompanying drawings in which- Figure 1 is a longitudinal vertical section of the machine as mounted in a building,

elevation,.Fig. 2 is a detail longitudinal vertical section of the apparatus some parts being shown in elevation, Fig. 3 is a sectional detail of a safety vent used in the machine, Fig. 4 is a rear end elevation, parts being broken away, and 5 is a front end elevation, some of the parts being broken away. 4

The apparatus consists generally of a series of cylinders set at an incline and driven by` means of spiral conveyors and within which itis successively treated for' Washing out the oils by means of a solvent such as gasolene, rewashing for the purpose of securing any oils which may have escaped the first operation and steamed for the which may have remained in the material after the rewashing. The Vmaterial is fed to the lower end 'of the first cylinder through a hopper and as it is moved through this cylinder by the action of the conveyer, is washed by the solvent which is delivered to it through perforations in\ the conveyer shaft, the oil and solvent escaping receptacle.

from the-cylinder through numerous small perforatlons in its wall to a receiving jacket withln which the cylinder is inclosed and from whlch'they are'drained to a suitable The drain pipe is so located that the 1i uid accumulates within the jacket and t e lower end of the cylinder toa level above the throat of the hopper thus constitutlng a liquid seal for preventing the escape of vapors through the hop- .A

per. From the upper endof the first cylinder the material falls through a connecting pipe to the lower end of the second cyllnderthrough which it is passed and treatf ed in similar manner, a liquid seal being there maintained if found desirable for preventing vapors from passing back into the first cylinder. From the'upper end of the second cylinder the material falls through a connecting pipe into the lower end of the e 'third cylinder through which it is passed 1n the same manner and from which it is discharged' througha discharge pipe. In the third cylinder there is forced into the material through a hollow and freely perforated'shaft of the conveyer, live steam which vaporizes any-ofthe solvent which may have ond cylinder, the vapors escaping from the inclosing jacket through pipes leading to a suitable condenser. IIn order to prevent vapors from passing back from the third cyl- Inder into the second an vannular series of fine steam jets are delivered into the pipe connecting these two cylinders being directed obliquely downward and in order to prevent the escape of vapors through the discharging nipple a similar series of steam jets enter this nipple being directed 0bliquely upward.

The receivinghopper is shown atlO and as delivering at 11 to the lower end of the cylinder 12 which is inclined upwardly, as s lown, at an angle of about twenty degrees. This cylinder is inclosed through the major portion of its length within a jacket 13, the

perforated, as indicated at 14. A splral conveyer 15 is located within the cylinder 12, extending throughout its entire length and being fixed upon a tubular shaft 16 journaled in the ends of the cylinder. A pipe 17 leads tothe upper end of the shaft 16 with which it is connected by means of' a lnclosed portion of the cylinder being freely thus raising their 4 which r discharge pipe 37, drain pipes 38,

terial escape from thecylinde through the perforations /14 into e jacket 13 from which they are discharged through a pipe 20 communicating with a receiving tank 21.

-The pipe 20 is connected with the jacket 13 at a point sli htly above the throat of the hopper l1 an 'as aconsequence the liquids accumulate within the lower end of the jacket and cylinder so-as t6 seal the hopper throat. The pipe 20 is-provided with a -valve as indicated at 22, by means of which the discharge of the liquids may be retarded level within the jacket and cylinder. Drain pipes 23, 24 lead from the jacket 13 at lower levels than the pipe 20 and aiford means for com letely discharging the jacket and cylin er of their liquid contents. These drain pipes are 'provided with valves as indicated at 25, 26. A drain pipe 27 having a valve 28 leads from the extreme lower end of the cylinder 12. All of the drain ipes are shown as communicating with t e tank 21.

From the lower side of the upper end of the cylinder 12 there leads a pipe 29 through the material is discharged into the lowery end of the second cylinder 30 which with its accessories may be an exact.dupli cate of the cylinder 12, there being resent a spiral conveyer 31 mounted on a ollow shaft 32 journaled in the ends of the cylinder and having numerous line perforations '33 opening vto the interior of the cylinder; a

jacket 34 inclosing the cylinder through a major portion of its length, the portion of the wall of` the cylinder which is thus `inclosed, being freel perforated as indicated at 35; a pipe'36 ty r delivering the solvent liquid to the upper end of the shaft 32; a 39 and 4o, all provided with valves and leading from the jacket 34l and the cylinder 30 to a,y receiving tank 40% From the lower .side of the upper end 'of the cylinder 30 there leads a pipe 41 for delivering the material to the lower end of the third cylinder 42. This cylinder Jwith its accessories diiers but slightly`\ from the cylinders 12 and 30 beingrinclosed through the major portion of this length within a jacket 43 and there being within it a spiral convyer 44 fixed u on a tubular shaft 45 to t e u per end o which there leads a pipe 46 an which is freely perforated, as shown at 47', to discharge into the cylinder 42. Drain pipes 48, 49 lead respectively from the lower ends of the 'acket 43 and cylinder 42 to a receiving tan 50 and a header 51 ycommunicates with. v,the chamber of the' jacket 43 by means of a 1'plurality of vni plls, t e

as 52, 53 and 5.4 whic lead throug vup er side of,the wall of the jacket, a ipe 55 eading y in coil 56. lA pipe 57 leads from the lower si e of the cylinder 42 atits upper end.

hollow belt 58 encircles they pipe 41 andto this belt there leads a pipe 59. An annular series of. downwardly inclined ports chamber of the pipe 41 adjacent the'loWer end of the latter. the ipe 57 a pipe 62 leads to the chamber of 't e belt and an annular series of u 7 wardly inclined orts 63 lead fromA t e chamber of the bt to thefchaiber of the pipe 57, entering it near its upper end.

The conveyers of the several cylinders are driven by means of a belt pulley 64 mounted upon a shaft 65 carrying pinions 66,67 and 68 meshing with gear wheels l69, 70 and 71 fixed respectively .upon the shafts.16, 32 and 45. t The solvent is supplied to the c linder 12 through the pipe l17 by means o a pump, `conventionally shown at 72, the pump drawing from any suitable reservoir. In practice it is feasible to regard the tank 40 as the source of supply and inthe drawings the suction side of the pump is shown as being connected with this reservoir by means of the pipe 73.

The liquid'discharged from the cylinder 12 is received in the tank 21 and consists of an admixture of gasolenehoil and-considerable refuse matter. The oils separate out to someextent and Heat on the gasolene. An overflow pipe 74 leads from this tank to a vaporizer 75 of any desirable construction where the volatile solvent which has been carried over with the oils is vaporized and passes through the pipe 76 to the coil 56, and thence through t e pipe 77 to the receiving tank 78. The oils and the refuse carried by them escape from the vaporizer 75 through a pipe 79 to a suitable separator represented at 80. i J j The solvent for the i'e'wash of the material is fed to 'the cylinder 30 from the tank 78 by means of a pump 81 connected therewith on its suction side by the pipe 82 and delivering through the pipe 36. The liquids discharged from the cylinder 30 are received.`

' -any danger from explosions should a fire be cylinder 42 are the pipe 55. Any liquids lwhich may accumulate in the jacket 43 are led'therefrom by the pipe 48 to the Atank 50 from which ,they are drained through the pipe 84 to the receiving tank 78, assing through a tra 85, of any approved) form, where water, i any be present, 1s eliminated.,

Safety vents 86,87 are provided for the cylinders 12 and 30 in order to.l eliminate accidentally developed within these cylinders. The cylinders themselves are made ofsufiicient strength to withstand a high deee of pressure. Each of the vents 86, 87 1s closed by means of 'a frangible plate 88, preferably of lass, which will yield to a pressure much elow that which the walls of the cylinders are capable of withstanding. The apparatus is shown in the drawings as l being mounted in a building havin two fioors. The pumps, vaporizer, con enser, separator and final receiying tank are l0- cated in the lower compartment, the floor of which is represented at 89. These parts of the apparatus are in common use and formf no p art ofthe present`invention.@ T e several cylinders and the tanks asso'- J ciated therewith are mounted upon the floor 90 of the upper compartment and are carried by any suitable frame; as 91 more lainly shown'in Figs. .4 and -5. s this ame may be designed according tothe jud ent of the manufacturer, it need not be ascribed in detail. There may be associated with the cylinders 12 and 30 a glass gage for showing the level of the liqui within the cylinders. In Eig. 5 such a gage 92 is associated' with the' cylinder 12.

In thewashing operation the solvent is not' only dischargedthrou h the material radially but by reason of tige inclined position of the cylinders it gravitates downwardly-through the mass toward the lower end of the cylinder and its ,action in the material lis thereby prolonged.' 1
